You basically do FTP-SSL by using an ordinary ftp:// URL and setting the
CURLOPT_FTP_SSL option. And yes, the CA cert "problem" you refer to above also
applies to FTP-SSL.

(You can also use ftps:// URLs, but that is a deprecated approach according
to the standards.)

Try this:

         curl -k --ftp-ssl ftp://mysite.com/

curl adheres to the FTP-SSL/TLS suggested standards so you can pick any server
that does the same. Paul Ford-Hutchinson maintains a list on his page:
